ATTACHMENT FOR TRIMIHING MACHINES.

Application filed May 3,

To all whom it may concern:

Be it known that I, HENRY RENKEN, a citizen of the United States, and aresident of the county of Queens, in the city and State of New York,have invented certain new and useful Improvements in Attachments forTrimming Machines of which the following is a specification.

My invention relates to improvements in attachments for trimmingmachines and an object thereof is the provision of a gage adapted to beattached to the table of a trimming machine wherein the wear in the gageand along the rail which carries the gage is automatically compensatedfor.

In general, my attachment comprises a sliding stop adapted to be mountedupon the work table of a trimming machine, this stop positioning thework to be operated upon, means being provided whereby this stop may beadjusted accurately at all times and with the least possible effort.

The gage constituting the major part of my invention has one endrigidily secured to the work table and another part secured to theadjustable stop above mentioned, a floating connection being providedbetween the fixed portion of the gage and that portion carried by thestop so that all wear is automatically compensated for and does notthrow the attachment out of alignment.

In the accompanying drawings,

Fig. 1 shows my improved device in elevation and applied to the worktable of a trimming machine;

Fig. 2 shows the device in plan; and

Fig. 3 shows the device in section, this figure being takensubstantially on the line 33 of Fig. 2.

Referring to the drawings in detail, 1 designates the work table of atrimming machine and 2 an adjustable stop adapted to slide along theguide 3 of the table. 4t indicates a piece of work to be trimmed,mounted on the work table and engaging the adjustable stop 2. Secured tothe side of the work table and adapted to slide along the guideway 3 isa block 5. This block is held in adjustable position by thumb screw 6.The block 5 comprises or carries a yoke or bracket 7 this bracketreceiving a straight sided floating block 8 adapted to have verticalmovement in the bracket 7 This floating block 8 is pinned or otherwisesecured to a threaded spindle 9. The stop 1922. Serial No. 558,321.

2 is provided with e pair of guide brackets 10 and 11, these bracketsbeing spaced from each other to accommodate a hand wheel 12 which isthreaded to receive the spindle 9. In operation the block 5 is set atany desired position along the guideway or rail 3 of the work table andsecured in position by the thumb screw 6. The work 4: is then placed onthe table and pushed against the stop 2. By manipulation of the handwheel 12 the stop 2 may then be adjusted toward or away from the side 13of the work'to be trimmed, the spindle 9, it being understood, beingheld against rotation by engagement of the floating block 8 with thesides of the bracket 7 carried by the fixed block 5. The threads on thespindle 9 are fine pitch so that the work 4; may be adjusted veryaccurately. By reason of the fact that the floating block 8 is permittedto move laterally so as to have vertical movement with respect to thebracket 7 it will be seen that any wear of the rail 3 or the guidewaysin the stop 2 which cooperate with the rail 3 will be automaticallycompensated for so that the stop will always properly engage the rail 3and will not be thrown out of alignment therewith. It will be readilyseen that if the spindle 9 were rigidly secured to the block 5 any wearbetween the stop 2 and rail 3 would place a strain on the spindle 9 andblock 5 to throw the attachment out of proper adjustment and alignment.

Another important advantage of the present attachment is its simplicityof construction and the ease with which the stop 2 and block 5 may beadjusted along the side of the work table 1.

I claim:

1. In a trimming machine, the combination of an adjustable stop,'amember coop crating therewith and adapted to be rigidly secured to theside of the work table of the machine and a floating connection betweenthe stop and said member.

2. In a trimming machine, the combination of a block adapted to berigidly secured to the work table, a stop carried by the work table, aspindle adjustably connecting said block and stop, said spindle beingfreely ing the block in adjusted position, a stop carried by the Worktable, a spindle connecting the block and stop and adapted to adjust thestop on said table, and means for attaching one end of the spindle tothe block, and permitting of lateral movement of the spindle relativelyto said block.

4:. In a trimming machine, the combination of a block adjustably mountedon the Work table of the machine, means for securing said block inadjusted position, a bracket carried by said block, a floating blockcarried in said bracket, a spindle rigidly secured to said floatingblock, a stop, guide brackets carried by said stop and receiving saidspindle and a hand Wheel threaded on said spindle and mounted intermediate said brackets whereby When said hand Wheel is, rotated thestop will be moved along said rail.

This specification signed this 2d day of May 1922.

HENRY RENKEN.
